we plan to overhaul our Touch Bar support in one of the next major releases to be context sensitive. This would of course include showing the f-keys and other common Windows keyboard shortcuts in RDP sessions.
In the meantime you can also configure the OS to always show the f-keys for specific applications (Royal TSX in this case). See this stackexchange answer for instructions on how to configure this: https://apple.stackexchange.com/a/283570/51314
I have a new 2017 MBP with touch bar. I know that I can tell OS X to give me the F-keys (F1-F12) by default, but I don't want to do that globally.
I just want F1-F12 to be displayed when the input is focused at RoyalTS RDP session.
Is that something that we can have an option for?
